Vise



Patented Nov. 11, 1941 UNITED STATES PATENT OFFICE VISE Ferdinand F. Olsen, Quincy, Mass.

Application July 8, 1939, Serial No. 283,348

Claims.

This invention relates to new and useful improvements in vises, and it has for its main object to provide a vise, in which the jaws, through a sliding process, may be adjusted to the size of any object to be engaged, contrary to the now common use of screwing said jaws together.

As the construction of my device is comparatively simple, the cost of manufacturing the same should be proportionately low.

With the above and other objects in view, this invention consists of the novel features of construction, combination and arrangement of parts, hereinafter fully described, claimed and illus-- trated in the accompanying drawing forming part of this application, and in which similar characters ofreference indicate corresponding parts in all views, and in which Figure 1 is a perspective view of my invention.

Figure 2 shows a transverse sectional view, taken on the line 2-2 in Figure 1, and illustrating clearly the relative arrangement of the parts constituting said invention.

Figure 3 is a detail view of parts of my invention, partly in section, and showing especially,

what may be termed a vise-lock in a released consisting of two members II and II, made of case-hardened steel, said members are secured to the base by means of screws I2, as may be seen in Figure 2. The track members II and II are upon the inner half of their lower surface provided with teeth I3, as may especially be seen in the Figures 2 and 3.

The base of the vise is at one end thereof formed with a shoulder I4 to which is attached a jaw member I 5, made of tool-steel, hardened and ground, while the other jaw member I5 is secured to a block I6, which in turn is adapted to slide upon the track members II and II.

Said block I 6 has a rod I! mounted therein; upon the end of said rod I1 is secured a sleeve I9 by means of a pin 20; a handle I8 is in turn pivotally mounted in the end of said sleeve and secured thereto by means of a pin 2|. The rod I! enters the end of the block I6, as said rod is threaded in an opening 24 in a separate piece 22, which latter piece is hardened steel and in turn positioned in the block I6. The piece 22 is secured to the block I6 by means of pins 23.

The end of the rod II terminates in a ball 25 adapted to fit a locking member 26, said locking member, which is mounted upon the rod I1 and the ball 25, has an opening 21 therein, through which opening the rod I'I passes, said opening 21 is made with a diameter slightly larger than the diameter of the rod in order to permit a certain play or wobbling of said locking member with respect to the rod IT. A part, or member 28, which has its inner surface made to fit the head of the ball 25, is secured to the locking member 26 by means of a screw 29. The lower part of the locking member 26 is formed with an opening 30 adapted to receive therein a rod 3|, said latter rod is inserted into the block l6 through an opening 32, and the rod is upon one end thereof made with an enlarged portion 33 adapted to engage and fill out said opening 32 into which opening said enlarged portion is pressed or forced; the other end of the rod 3| is mounted in a recess 34 in the front of the block I6. Upon the rod 3| is mounted a spring member 35; one end of said spring member rests in an enlargement 36 of the opening 34, while the other end of the spring member rests against a washer 31, which washer covers the front of the elongated opening 30 in the lower portion of the locking member 26; the opening 30 being considerably larger than the diameter of the rod 3|, which passes through said opening, thereby permitting a tilting movement of the said locking member with the ball 25 as the fulcrum.

The locking member 26 is upon both sides of its lower portion formed with shoulders 38 upon the upper surfaces of which are formed teeth 39, as may be seen in Figure 4.

The block I 6 is upon its rear surface, and above the opening 32, formed with another opening 40 into which latter opening is inserted a block member II, which is upon the front thereof formed with a beveled surface 42 adapted to engage the member 23 of the locking member 25 upon advancing the threaded rod IT in an inward direction, thus returning the locking member 26 into a vertical or released position, as shown in Figure 3. The spring 35 is then, due to the swinging motion of the locking member 26 around the ball 25, being compressed, while the teeth 39 are disengaged, as shown, from the teeth I3. This will permit a free sliding movement of the block I 6 upon the track members I I, II for quick adjustment from one object to another of varying dimensions.

Figure 2 shows the vise in a locked position and holding an object 43. It may in this connection be noted that when the threaded rod is retracted or turned in an outward direction, the locking member 26 will be disengaged from the block 4|, while the lower end of the locking member, due to the expanding of the spring 35, is swung inwardly until the teeth 39 engage the teeth 13. When the upper edge of the opening 21 comes to rest against the rod I1, the block I6 is then forced forward, thus clamping the object 43.

As may be clearly understood from the foregoing description, only a few turns of the rod 11 are required to bring the vise from the locked position into the released position, or vice versa.

It is obvious that changes may be made in the construction, combination and arrangement of parts within the scope of the appended claims, without departing from the spirit of my invention, and I do not, therefore, wish to limit myself to the exact construction shown and described herein.

What I claim as new, and desire to secure by Letters Patent of the United States is:

1. A drill press vise comprising a base, the latter terminating at one end in a shoulder, a track consisting of two members formed with teeth thereon and being rigidly mounted upon said base, a block member adapted to slide upon said track, means arranged upon said block member and shoulder, respectively, whereby to securely engage an object, a rod terminating in a ball and being threadedly mounted in said block member, a locking member loosely mounted upon the rod and upon said ball, and an endpiece adapted to fit one end of the ball and being secured tosaid locking member, the latter being upon the lower portion thereof formed with teeth adapted to engage the teeth of the track, said lower part of the locking member being formed with an opening therein, the block member being in the lower front thereof formed with an opening terminating at its rear end in an enlarged recess, said block member being at its rear end formed with two openings therein, a rod mounted in the opening in the lower part of the locking member,

, and in the openings in the lower front of the block member and the rear thereof, said latter rod being formed with an enlarged end portion rigidly secured in the lower opening in the rear of the block member, a spring mounted upon said latter rod and adapted to actuate the locking member during operation, and a small block formed with a beveled surface and arranged in the upper opening in the rear end of the block member, substantially as and for the purpose set forth.

2. In a device, as claimed in claim 1, and wherein the spring has one end thereof disposed in the enlarged recess of the opening in the front of the block member, a washer arranged upon the lower rod and in front of the opening in the lower portion of the locking member, said washer being adapted to support the other end of said spring.
